Question

I wanted to count number of characters in a string which I pull from div tag like this:

$(".welcome-msg").html().length;

However it’s counting HTML comments as characters inside the tag. So when I would like the result to be 0 I get 99 because of those comments and I don’t have a way of telling if comments are dynamic or not. Is there an easy way to make sure comments are not counted? Or do I have to write regular expression for that?

Thanks,

Answer 1

var myhtml = $(".welcome-msg").html();
myhtml = myhtml.replace(/<!--.*?-->/sg, ""); 
myhtml.length();
